In Scala Stack class, the pushAll() method is utilized to add the elements from a collection to a stack.
Method Definition: def pushAll(elems: IterableOnce[A]): Stack.this.type
Return Type: It returns a stack that contains all the elements of the given collection.
Example #1:
// Scala program of pushAll() // method import scala.collection.mutable.Stack // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a stack var s1 = Stack[String]() // Creating a set var s2 = Set("C++", "Java", "Python", "Scala") // Print the set println(s2) // Applying pushAll method s1.pushAll(s2) // Print the stack println(s1) } } |

Output:
Set(C++, Java, Python, Scala) Stack(Scala, Python, Java, C++)
Example #2:
// Scala program of pushAll() // method import scala.collection.mutable.Stack // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a stack var s1 = Stack[String]() // Creating another stack var s2 = Stack("C++", "Java", "Python", "Scala") // Print the stack println(s2) // Applying pushAll method s1.pushAll(s2) // Print the stack println(s1) } } |
